Abstract:
A slurry composition for a non-aqueous secondary battery negative electrode contains a negative electrode active material including lithium titanium oxide, a binder, and an organic solvent. The binder includes a copolymer that includes a nitrile group-containing monomer unit and at least one selected from an aliphatic conjugated diene monomer unit and an alkylene structural unit and that has a Mooney viscosity (ML1+4, 100° C.) of not less than 50 and not more than 200.
